It's difficult to tell which are no longer used.  For example, I was recently asked about the Reliable Data Protocol, it’s IANA assignment:

27	RDP	Reliable Data Protocol		[RFC908][Bob_Hinden]

I assumed it was no longer used.   Later by happenstance, I learned it is specified by ETSI as mandatory to implement in eSIMs.  I had no idea.
