But in general, yes, any DWARF expression that contains a DW_OP_addr might need
a relocation for its address argument.

Are you aware of where in the standard this is documented? It sounds reasonable
but I'm returning to this after a long time and I don't remember my way around
as
well as I used to.
DW_OP_addr is described in Section 2.5.1.1 of the DWARF 5 Standard:
2. DW_OP_addr
The DW_OP_addr operation has a single operand that encodes a
machine address and whose size is the size of an address on the
target machine.
The most common way in which the machine address is provided as the
operand is by generating a relocatable value pointing to the target
address. This is not really a DWARF specification; it is how
relocations work in assemblers and linkers.
