It’s very much on the list, but will probably have to wait for a few other things to be rewritten first (SSL and DNS specifically) as they touch so much, but it’s pretty much next on the list.
What I’m working toward is that things like Apache and PHP are fully configurable; specific versions for sites via FPM, (optionally) separate chrooted users for each site, easy to configure back-ends behind Apache, switchable PROXY protocol settings, and things like that.
Theres a lot on the roadmap, and it’ll take a good while to cross them all off, but development is ongoing to deal with the technical debt from Symbiosis, at which point it’s full steam ahead.
