Hi,

sorry if completely off the mark, but doesn't babel provide the

\@safe at activestrue

toggle precisely for such \csname...\endcsname expansions ?

Couldn't crossreftools in presence of babel do

\@safe at activestrue
...

\@safe at activesfalse

or see hyperref code on how to do this in a way which will work
even without babel \if at safe@actives

I don't read tex.sx, so perhaps this has been mentioned

I hardly read this thread either, so I may be making noise.

But clearly, it is on crossreftools to adapt to babel shorthands
