Couple of important points here:
1)Getting super excited whether pro or con in Bitcoin at very early testnet stages is bound to often be disappointing. Many things in Bitcoin were "definitely" coming and "definitely" going to be the next big thing on Bitcoin and they went nowhere. I suggest not getting emotionally invested or bother going too deep (unless you're a dev thinking about working on them) until they at least get to working code on mainnet.
2) Where is demand and what is the compelling product market fit? I'm skeptical. I also don't see a strong use case proposed amidst any article I've seen that will grab the average pleb or Bitcoin business. The market does not appear to either as evidenced by no one really being that interested. In all of these articles I never see what any tech project always needs: a super clear and compelling use case that can be explained in 1-3 sentences with little or no technical jargon. Do we really need more tokens and DAPPs (the 2 main use cases cited on Botanix's website)? Despite high fees Liquid is still mostly empty after years of mainnet deployment and development by one of the best bitcoin companies. Why would this get used when almost no one has touched Liquid for 6 years?
3) Security model, I'll politely summarize that I am skeptical. At least I would want to see it deployed with significant volume and have no security issues for a full year or more before I'd even consider touching it. Especially when you're at the proof of concept stage and there is no economic value to be stolen/gamed/scammed it's hard to know what issues could arise even beyond code such as misaligned incentives, exploits, etc. Directly quoting the Bitcoin Magazine article, "As long as the size of individual multisigs are balanced right with the total number of stakers, and the value of all deposits compared with staking bonds, this could be a very workable system." I will say it differently, this is still at the conceptual stage and may work or it may not. If you want to use if/when it makes to mainnet please consider only using small amounts to start.
4) Eth/shitcoin ick factor is not to be underestimated. This will keep a huge portion of Bitcoiners away for a long time(myself included admittedly), maybe forever unless the use case just becomes overwhelmingly compelling. I'm never touching anything that needs metamask, full stop. Why do really we need an EVM sidechain? I'm not saying it's useless. I'm only saying to the average pleb Bitcoiner it doesn't jump out as important or essential to invest time & energy into, and most businesses are still just trying to understand the base layer so they aren't getting anywhere near this any time soon.

With most things like this I think its best to wait and see. If you are excited and have some technical skills its great to go through the Github repo and consider contributing. But getting emotionally invested in whatever the hot new thing in Bitcoin will be is probably just a road to constant disappointment and disillusionment. Bitcoin doesn't need anyone to save it. The market and economic incentives will keep the ecosystem working and vibrant over time.
