Not in my experience. LTS never seems to break any compatibility, even internal kernel structs, function names, etc.

Actually LTS does break ABI, but gregkh is working with Android to make a partially ABI-stable LTS (I assume it would be a fork of the real LTS though?).

I know they are also working with RH and Suse, but I don't know if RH and Suse will only share the tools, or will also have the same LTS source tree.

When I say "partially-ABI" stable, their goal is to list acceptable symbols and automatically verify that vendor modules use those symbols, and only those accceptable symbols are ABI-stable.

That "partially-ABI stable" is the same exact thing that Red Hat and SUSE and Debian have been doing for 20+ years now. Nothing major and exciting there, but see the presentations at the Linux Plumbers conferences for details on the tools being used if people are curious (hint this time everyone is working together on the same set of tools...)
