Ok, looks (or, at least, reads) good.  Unfortunately, I can not verify, 
since my freshly updated and compiled cvs lilypond core dumps on this 
file (*** glibc detected *** lily/out/lilypond: free(): invalid pointer: 
0x08d6b818 ***).

So, currently being somewhat blindly, could you please double-check that 
there are no bars visible in the template?  When, beforehand, I tried with 
2.7.35, an additional '\remove "Bar_engraver"' was required in Staff 
context.

Mmmh, well, it's neither a semantically clean nor a typographically 
correct solution.  I would call it a workaround...

Did you try setting "barAlways = ##t" in Score context?
