My understanding of the situation is that the bugs only affect
interpretation of PROXYv2 headers.

PROXYv1 should work in v4. At least, it is being used by several testers.

One thing to note is that PROXY protocol requires clients send the
entire header as one packet such that it is read as one operation by the
receiver. Those recipients are *required* to reject PROXYv1 that do not
arrive as a single I/O.
