I think it is not "allowed" but "mandatory to implement". We should
allow implementations to support an ftps:// scheme as long as there
is a common baseline.

<tp>
I am confused.  Is ftps: intended to be an existing scheme or a hypothetical 
one that may appear in the future.  I do not see it in the IANA registry
https://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml#uri-schemes-1

sftp: appears as a provisional entry in the IANA registry but AFACT did not get 
specified.  I recall a debate about ftps: v sftp:  I favoured the former but 
lost but then I did not see any further work on either.
