I believe it was added by Joe Neeman in order to fix issue #442:
https://sourceforge.net/p/testlilyissues/issues/442/

You can’t say it’s undocumented, its documentation is just not meant
for regular users:
http://lilypond.org/doc/latest/Documentation/internals/keep_005falive_005ftogether_005fengraver
There are also several comments in the source code:
