Right, as far as I understand, support for Emacs 24.3 was the main
reason to avoid it; subr-x.el wasn't added until Emacs 24.4, when it was
renamed from helpers.el.  (There may be the general stylistic question
of whether to use when-let{,*} and friends, but that's not relevant in
this context.)

I've pushed 04d9d4b3d, but please feel free to adjust as needed if some
other reason to avoid loading subr-x surfaces.
