There are a lot of terms in the master glossary for TCDB that are not listed in the document or even in what was called "THE List". There are a couple levels of the "A/As" (Abbreviations/Acronyms) that are used here:
1 - "Reserved" A/As - such as RC, SNxxx, PRxxx, ECH, VAR, COR, ERR, UER - these each have one meaning, and one meaning only, and when used in any set, the site auto-defines it for us
2 - "Preferred" A/As - Meaning that if we were wanting to use an A/A for "Strength & Conditioning Coach", the preferred A/A is "SCO", however, SCO can be used for other meanings (I can't think of an example right now, but you get the idea).
3 - "Set Specific" A/As - these are the ones that exist in only a set (or a couple here and there), but are not a universal thing. An example of that might be where a set has "Lamp Lighting Defensemen" as subset in the base set. Not sure if "LLD" is used anywhere else, but this would be appropriate for this set.
The above is site fact. The below contains my opinions (as well as some fact).
That said, XRC, as reviled as it is amongst some, its use in the hobby pre-dates this site, and there are plenty of people in the hobby that know the term, use the term, and might be a bit befuddled by the lack of such a term. As I gave in my example of the 1984 Fleer Update set, do we rip out the XRCs and leave them blank? Do we call them RCs? If so, what then happens to what the hobby has called RCs from the subsequent year? Do we have 2 years of RCs? Or do we ignore what the hoby has said for 35+ years.
I don't think it's as simple as eradicating all XRCs from the site, nor does that do any service to the hobby. There needs to be some sort of a "plan" for the XRC removal, and it needs to go before Admin before any action is taken.
I am not a fan of the blind removal of XRC. If there is a well-planned "exit strategy" and Admin is good with it, I'd be happy to help make that plan happen. Otherwise, I'm okay with XRC living on.
