nameref and gettitlestring #129
Description
It would be a nice feature for nameref to optionally use the expansion method of gettitlestring without setting the corresponding package option globally. This request is actually motivated by this discussion: latex3/latex2e#307
As soon as there are some user-defined commands which should be ignored for generating \@currentlabelname one has to use the expansion method of gettitlestring. Setting \GetTitleStringSetup{expand=true} globally is maybe error prone, although I do not have a particular case in mind.
Maybe using protected expansion at least in headings by default or via option would be good as well. See also ho-tex/gettitlestring#2 and ho-tex/gettitlestring#3 The expansion is already protected.
