If you do the development work to support hot protocol of the moment X, chances are in 18 months nobody cares because either (a) now X is old news and nobody uses that any more or (b) X+1 came out, it's incompatible and you'd have to do the work again for it to be useful.

If an enterprise customer will pay $$$ to support X this can still make financial sense, but Cloudflare's non-enterprise customers aren't paying $$$.

Minecraft is apparently not going anywhere, it's still very popular a decade after release. And my understanding is that the protocol is fundamentally the same as ever. So, you do that work once, and then you've got a free proof of concept apparently forever.
