The code looks goods. For future maintenance and ease of review, some additional comments would help.

test/functional/p2p_invalid_messages.py
294–295 ↗	(On Diff #48286)
296 ↗	(On Diff #48286)	Maybe add a comment that `size - 5` works for this particular compact size range `0x10000 <= size < 0x100000000`.

test/functional/p2p_invalid_messages.py
315 ↗	(On Diff #48286)	The node won't start if excessiveblocksize < DEFAULT_MAX_BLOCK_SIZE. Here also a comment would be useful for future maintenance.

test/functional/p2p_invalid_messages.py
296 ↗	(On Diff #48286)	I am considering a patch that bumps this arbitrary value to `str_data=b'\xff'` everywhere because I ran into the limit when writing the new tests. I can include the comment in that patch.
