Hi everyone, On the occasion of a "guix pull", I looked into this issue again, because magit without ido-completing-read+ is less fun.
Loading this package runs lots of compilation threads, but it does ultimately terminate, with an error: Debugger entered--Lisp error: (native-compiler-error (lambda (arg3 &optional arg4 arg5) (let ((f #'call-interactively)) (funcall f arg3 arg4 arg5))) "Debugger entered--Lisp error: (native-compiler-err...") signal(native-compiler-error ((lambda (arg3 &optional arg4 arg5) (let ((f #'call-interactively)) (funcall f arg3 arg4 arg5))) "Debugger entered--Lisp error: (native-compiler-err...")) comp--native-compile((lambda (arg3 &optional arg4 arg5) (let ((f #'call-interactively)) (funcall f arg3 arg4 arg5))) nil "/home/hinsen/.emacs.d/eln-cache/28.2-16da12a1/subr...") comp-trampoline-compile(call-interactively) comp-subr-trampoline-install(call-interactively) advice--add-function(:around (#f(compiled-function () #<bytecode 0x32e14019df7e91>) . #f(compiled-function (gv--val) #<bytecode 0x9f608bbba7cb3c2>)) call-interactively@ido-cr+-record-current-command nil) advice-add(call-interactively :around call-interactively@ido-cr+-record-current-command) load-with-code-conversion("/gnu/store/abvhh3kcdpbg9vm2jz5q6zqhmfdpr4m7-emacs-..."

It makes me wonder whether the problem is perhaps not native-compiling ido-completing-read+, but native-compiling the ido code that is getting adviced here. Cheers, Konrad.
