Considering things like perl etc. as being part of base, this would
mean that base would first have to be transitioned. Afterwards, parts
depending on base could be transitioned.

Why exactly? Just like we have had different versions of libc, gcc,
... in Debian (as a whole), we will have different versions of them in
"Debian-base" upon which the rest is built. What you mean with "chaos"
here, is what I mean with "other complexity" below.

Upgrades would only be possible in:

(1) base itself (of course)
(2) a subproject i.e. you cannot upgrade a "workstation" to a
    "mailserver" branch (this would be a migration instead of an upgrade)

That's what I mean. Try to remove complexity by restructuring
it. However, by restructuring things, you will also introduce other
complexities (i.e. most people feel it as complexity because it is
different/new).
