Are we? The first line of the Jhbuild wiki page still reads:

To me, changing this is a policy decision, so I'd like to have a broader
discussion about it.
+ less frequent breakages (only on manual updates)
+ maybe less total number of breakages (because some of them might be
already fixed in the meantime)
- we discover incompatible upstream changes only after a while when
upstream is less likely to change it
- regular manual updates needed
- need to track security updates and apply them ASAP (already a
nightmare for xulrunner)
An option might be to use different modulesets in parallel (latest deps
+ latest Sugar, stable deps + latest Sugar, stable deps + stable Sugar)
and have BuildBot instances for all of them. That way developers can use
a reliable system, but we still get notified of upstream breakages
We already use distro packages wherever possible, BTW (*). So this is
just about packages where the distro version (if any) is unsuitable to
Sugar, usually either because it's an "old" distro version or we're
relying on very recent features.
(*) If you find out that for any package we currently build on our own
the distro version in fact suffices, please file a bug against
sugar-jhbuild. I have little to no information about which versions or
features we actually need.
