So how does this affect actual loading of the system. Is it large enough for

For industrial users, certainly...

I can remember that when I worked in a factory, the leccy board came
around and wanted to redistribute the soak test racks and other things to
different mains phases due to imbalance of power factor due to the method
the ssets used to get power.
It always made me wonder how, if this was so bad, why it made no difference
when they wer in peoples homes.

Domestic users are far less likely to have a PF significantly below
unity, and if they do, it tends to be down to harmonic content rather
than classical voltage current phase mismatch.
