I think it depends in what fashion. We've been talking about supporting
building out-of-tree modules with "pgxs" for at least a 5 year support
window. But the replacement isn't yet finished [1], so that clock hasn't yet
started ticking.

The autoconf task is actually doing quite useful stuff right now, leaving the
use of configure aside, as it builds with address sanitizer. Without that it'd
be a lot faster. But we'd loose, imo quite important, coverage. The tests
would run a bit faster with meson, but it'd be overall a difference on the
margins.
