A branch is is supposed to be internally consistent: for any X and Y,
the latest version of X from a given branch is in theory compatible with
the latest version of Y from the same branch. If they are not
compatible, there should be a bug that somebody is actively working on
resolving, or a blocker dependency, and such blockers ought to be
relatively rare to make things easy for human minds and package
managers.

Masked packages are not a third branch. Some packages are hardmasked for
being untested, some for impossible-to-fix bugs, some are known to break
a reverse dependency and are waiting for that reverse dependency to be
updated, some are lastrited for removal in 30 days. There is absolutely
no expectation that all masked packages are compatible with each other.

Stablereq for wine-1.6.2 was filed in February. It got stabilized on
amd64 exactly 4 months later.

Security stablereq for freetype-2.5.3-r1 was filed in March for all
arches. Thus far, only hppa and ia64 stabilized it.

People don't bother with filing stabilization requests because they
realize that arch teams usually have a long backlog of existing
requests, and might take weeks/months to get to your new request.
Especially if your new request depends on other stablereqs.
