I do have the text, and there is no such "recommend[ation]".

It says

      ".invalid" is intended for use in online construction of domain
      names that are sure to be invalid and which it is obvious at a
      glance are invalid.

That is not a recommendation for anything -- it is a statement of intent;
intent for use "online" and not via hard-coding -- and is certainly not
a recommendation for use in address fields.

You have missed the point.  Evidently you haven't looked at RFC

I have now looked at RFC 3696, and what Usefor proposes seems entirely 
consistent with same. Essentially, it says that if you intend user
agents  to check for and act upon particular TLDs, then you need to be
pretty sure  that  your filtering is fully consistent with the relevant
published  specifications. A registration with IANA that a given TLD
will _never_  resolve to anything seems as clear in that regard as one
can get.

You have utterly missed the point of RFC 3696. The point is that
hard-coding domain names is foolhardy; whether that is a hard-coded
assumption that TLDs are 3 characters, or that specific strings are or
are not TLDs, etc.  And you have far too much faith in IANA; RFC 2046
reserves the name "ASCII" which is not supposed to be used as a charset
name or alias -- yet IANA has registered it as a charset alias.  Now,
IANA doesn't control TLDs, ICANN does; whether you have more or less
faith in ICANN vs. IANA is another matter...
