AFAICT you're proposing a file structure for maintaining several sets of
configuration files for different network environments.
That will definitely be necessary, and fits in nicely with what I meant:
/etc/network-param-changes.d (or whatever) is filled with shell scripts,
installed there by various packages.
The moment your /run/etc-profile symlink changes, all those shell scripts
are run with run-parts. But they'll also be run if a DHCP server suddenly
decides to give you a different DNS server.
