Well, that's specifically for mains. There's good reason it doesn't
mate with regular speakon even though the principle is the same.
I understood the conector in question was to be used for low voltage
DC, that is, +/- 15V, so powercon probably is even less of the right
thing to use compared to speakon.

Indeed it likely doesn't happen too often, especially when people are
aware of the possibility. Actually, at one of my former employers, we
were using the 8 pin speakon variant for exactly this purpose. Granted,
High-Speed optical communication very rarely is used together with PA
systems, and 8 pole speakon is a rare beast in itself, even in PA
systems, but still, one customer managed to do exactly this. Luckily it
was only the power supply that got fried, otherwise it would have been
a six-digit figure loss.
Of course, in the end its a matter of personal decision, and as long as
it's clear what is used for what and what should not be connected. I
myself prefer to make sure different uses are impossible to mate even
by accident, but there's only so much you can do. There's always the
possibility that the connector you chose is used differently somewhere
else. But you can make such accidents less likely by using different
connectors. If all your speakers use 3 pin XLR, speakon probably is
safe for DC.
