If I had one of those, it would just be run at 240V and the lack of neutral would not be a problem.

If they have a power demand that exceeds a 15A circuit, putting it all on a
15A circuit is a bad thing regardless of whether the power strip is the right type or not. Still, it can make for less safe usage when people cut off the plug and insert their own.
I have seen a 5-20P -> multiple 5-15R strip. It was presumably intended for the larger cases of usage. Maybe they also make a 5-20P -> multiple 5-20R or even 5-20P -> multiple 5-20RALT.
But what I want is the 6-15P or 6-20P strip that has 6-15R or 6-20R outlets. I'd rather have that over the readily available Schuko strips because the surge protection within could be correct with respect to the voltage clamp level for the conductor to ground MOVs (needs to be based on 120V supply as in North America rather the 230V supply as in Europe).

I still occaisionally see some that do not have the switch/breaker.
I will need to investigate the usability of the "whole house" panel protectors (the kind that plug into 2 or 4 breaker panel slots) for computer rack.
