Having operated 'boilers' of every size/design for over 30 yrs the one thing I do know is about the SAFE operation of them.
Water heaters are just small boilers
Every component attached to boiler MUST meet the temp/press rating of boiler in order to be SAFE.
AND the smaller the hole the more restrictive is becomes when draining/flushing
Just saying....
Pretty sure a brass cockvalve is going to be safe when compared to a plastic plug.
Convenience of the cockvalve trumps the plastic plug for part timers.

I took my plug out completely and installed a 90 degree drain valve with a hose that is routed under the RV to drain.
Hope that hose is temp/pressure rated for above 210*F/150 psi
Temp/press that COULD be reached/exceeded should t-stats fail to shut down heating source
Drain hole is small to begin with (1/2")
Valve cuts that size down even more so effective draining of crud is hampered.
A little bit of overthinking here.
Why would a drain hose thatโs about 12โ long need to be temp/ pressure rated.
Or are you thinking of the Temp. Relief Valve.
I donโt full time in my RV so the โcrudโ buildup would be minimal to non existent and I drain my tank after every trip.
Itโs a modification that I wanted to do to my RV. If you donโt agree with it, then fine, move on to the next post but quit trying to impress everyone with what you think you might know.
