How much lint-catching is sensible at a washer standpipe?
A lint catcher could keep some material out of the drain, but if it clogs, the washer’s forceful discharge could back up and overflow. Are there catcher styles intended for standpipes, and are those different from the ones used at laundry sinks?
I’m curious what people use to spot a restriction early. Is reduced flow or water rising in the standpipe a dependable warning, or can a catcher clog quickly with little notice? How often it needs checking seems like a big part of whether the trade-off is worthwhile.

At a standpipe, I’d put the overflow risk ahead of catching every bit of lint unless the catcher is made for that setup and easy to inspect and clear. A sink catcher is easier to watch while water drains; with a washer’s fast discharge, I wouldn’t count on visible warning signs as a guarantee that you’ll catch a restriction in time.
