The most important question is the effect on users, and for users I
don't see why this method sucks.

testing:
Package: libv0
Version: 1
Package: proga
Depends: libv0
Version: 1
Package: progb
Depends: libv0
Version: 1
unstable:
Package: libv1
Version: 2
Package: proga
Depends: libv1
Version: 2
Package: progb
Depends: libv1
Version: 2
The way testing works, if both libv0 and libv1 can go into testing,
proga can enter testing years before progb.
If only one of libv0 and libv1 can be into testing, proga and progb have
to enter testing at the same time.
Exactly this was observed with KDE and GNOME:
KDE 2.2 in testing was horribly outdated, but it was consistent, and
when KDE 3 entered testing, a complete KDE 3 entered testing.
OTOH, the transition from GNOME 1 to GNOME 2 happened step for step, and
I know several people who switched to unstable since the GNOME in
testing was unusable.
