You can arrange for the settings to affect only some of the
subdirectories, the Emacs manual shows an example of that.

.dir-locals.el supports 'eval' forms, so you could in principle do
anything there. But my advice is to stick to simplicity, for reasons
of speed of visiting files, if nothing else. Also, maintaining such a
tricky file would need an Emacs expert, something that is not
guaranteed (although currently we have several on board).

IME, symlinks in versioned directories are a PITA.
