I suspect Anthony meant "uploads to unstable that bump shlibs": if
libfoo0 1.2 is in testing during the freeze, it is problematic to upload
a new libfoo0 version which will generate libfoo0 (>= 1.3) dependencies.

This is less clear-cut than it used to be, because of dpkg-symbols. If
libfoo0 adds a new foo_do_stuff() which generates libfoo0 (>= 1.3)
dependencies, but the rest of its symbols are still versioned 1.2, then
that isn't going to hurt testing migration for packages that don't use
that new symbol... unless there's some macro or inline function in a
header file that previously expanded to older code, but now expands to a
call to foo_do_stuff(), in which case libfoo users could "accidentally"
pick up new dependencies on version 1.3.
