I believe in the best of worlds, large print would now only be recorded in an RDA record in 340 $n. That said, in the RDA Appendix with MARC mappings, font size is mapped to both 300 $a and 340 $n.

In the original question, it isn't clear where (Large print) would be entered 
in MARC 300. In AACR2 MARC records, it is entered in 300 $a per 2.5B23, but 
there isn't a corresponding instruction in RDA. In RDA extent (300 $a) is 
limited to the number of units and subunits (3.4.1.1). Since Large print is not 
a subunit but a font size, how would including it as part of the extent (300 
$a) be justified in RDA? Although the RDA Toolkit has a link from AACR2 2.5B23 
to RDA 3.13.1.3, the instruction does not specify where to enter the Large 
Print information. Some MARC alternatives might be MARC 500 and/or 340. Maybe 
also 300 $b?

Is there a similar impact on AACR2 2.5B22?

What is core for RDA, and what is core for patron needs, are two
*very* different things!  AACR2 had a qualified GMD: "text (large
print)" which worked very well.  This is but one example of AACR2's
superiority over RDA in terms of meeting patron needs, as opposed to
conforming to theory.

To be fair, AACR2's GMDs are marked as optional and don't appear at all under 
1.0D's first level of description (which is on par with RDA's core 
cataloging--RDA for the most part follows in AACR2's footsteps).

If it's a matter of why 30-some years of GMDs and AACR2 practice never resulted in more 
elements being added to the "must have" pile irrespective of levels of 
description, I can't say.
