Yes, I think it has been inferred. LC-PCC-PS for says:
"If the name chosen for the authorized access point for a corporate body is an initialism or acronym written in all capital letters (with or without periods between them), add a qualifier to the name." (Variant Access Points) says:

"Make additions to the name, if considered important for identification. Apply the instructions at, as applicable."
As initialisms and acronyms are considered by the LC-PCC-PS to come under the category of names not conveying the idea of a corporate name, then clearly it becomes important to qualify them for identification.
The variant access point in the example at LC-PCC-PS for is itself qualified.
1XX, 4XX: same principle, different words.
We're applying a new standard; LCRI traditions can be left behind.

Subject: [PCCLIST] References from initialisms

I’ve noticed that qualifiers have been added to initialisms in many cross references, e.g.

410 2  CSS (Child Support Services)


and similarly on other references from CSS.  I’ve seen this on other initialisms.  Past practice was to record the initialism alone.  There is no requirement that 4XX fields not conflict with each other.  Has something changed?
