rebuilding using source

Hello:
	I have a system running:

FreeBSD 14.0-CURRENT #0 main-f0a15aafcb
Mon Oct 31 08:19:54 EDT 2022
amd64

	I want to bring current using source.
	In the past, I did so using the instructions at the bottom of
src/UPDATING.
	Now, however, there's this:

	To rebuild everything and install it on the current system.
	-----------------------------------------------------------
	# Note: sometimes if you are running current you gotta do more than
	# is listed here if you are upgrading from a really old current.

	But I also remember a semi-recent thread (may have been on
current@) that calls into question whether this is still the correct
procedure to use.
	1) did that thread ever come to a decision?
	2) if src/UPDATING is stil authoritative?
	3) if so, is this system so old I "gotta do more"?
	4) if so, where do I find instructions?


			Respectfully,
