The impact in terms of size seems to be quite small:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix size emacs|tail -1
total: 582.9 MiB
$ ./pre-inst-env guix size emacs libotf m17n-lib|tail -1
total: 595.2 MiB
--8<---------------cut here---------------end--------------->8---

So I went ahead and applied this patch.

How can one check whether it works?  Do users have to install m17n-db in
their profile?

Thanks!

No, users don't have to install m17n-db in their profile. They just need
to use the new emacs package built with m17n. m17n-db and m17n-lib are
just "inputs" not "propagated-inputs".

The difference with and without m17n is visible in the rendering of
Indic scripts. Tamil, one of the languages of South India, is the one I
use and tested.
