Is scan_interval a function of horsepower?

Im using the modbus integration and I get this

sensor clt_pump_act_speed scan_interval(1) is lower than 5 seconds, which may cause Home Assistant stability issues

I know from looking at the PR from back in 2021 that this was a warning - but does HA throttle scan_interval regardless of CPU/Bandwidth??? Ive got a i7 8 core machine running at 3.7ghz so Im not short of horsepower to be able to service something like this…
