Just to clarify: I suppose you mean using eval for things other than
which Emacs can automatically determine to be safe.  E.g.

    (eval . (put 'foo 'scheme-indent-function <n>))

for integer <n> is safe; Emacs will eval that silently if I'm not
mistaken.

But for things where Emacs pesters the user because it finds it
"unsafe," I find that very annoying.

IMO anything that can be put into .dir-locals.el without making Emacs
pester the user should be put there.  It's a delight for a Guix newb to
get such settings automatically, because otherwise M-q and TAB will
break existing correct indentation in edited source files, which is very
annoying, and also it might lead to extra patch review round-trips when
the user creates a patch with wrong indentation without noticing.

Just my two cents as a passerby in this thread...
