Yes, I think the way to go is to *always* have configs.
Basically a single-tree would be a special case with a trivial config.
Currently things that work more or less (with the help of some script
magic) is to have a checked out config and do things like update&commit on
all the subtrees.  But the interesting things begin when you consider the
problem of reacting to changes in the config.
E.g. your example of splitting a single tree into several smaller ones.
or changing the src/tla subtree from tla--devo--1.2 to tla--devo--1.3.
E.g. you should be able to branch a config where src/tla was moved to
src/foo and when merging from the top config, src/foo would be upgraded
from tla--devo--1.2 to tla--devo--1.3.

I think as long as such things don't work reliably, configs will stay some
kind of fiddly layering used for distribution, with a "use with care"
sticker on it.
