Code review comment for lp:~epics-core/epics-base/pcas-fake-dynamic

I am fine with the faking approach, as it is minimally invasive and still "fixes" things.

The CA Gateway (aka PCAS power user) always uses variable size subscriptions on its connections to the IOCs, so the "precious" IOC network already uses optimized traffic.
A "real" full implementation could follow at any time - the only difference would be the PCAS (CA Gateway) actually sending variable size arrays instead of always pushing the full size. No changes in protocol version, IOCs or clients would be required.
