But has anyone actually suffered from this?

I only need to move 15 miles West of where I live to get very hard tap
water. I have never heard of anyone there suffering from scale blockage on
washer jets.

I live in a hard water area. I've always used tap water to which I added the
appropriate amount of screen wash (concentration depending on
summer/winter).

Every few months I've found that my windscreen washer jets become partly
clogged: the flow out of one of the four jets (two jets per nozzle) starts
to become more feeble or maybe even disappears, requiring me to find a
suitably fine piece of wire to insert into the jet so as to unclog it.

I've always assumed that this is due to limescale building up on the jet.

The cheap stuff just doesn't work as well with the fan jet washers.
Although the proper VAG stuff is hardly expensive.

Then you are lucky. I normally use screenwash but when I ran out of
windscreen washer water a few days ago I had to use plain water from a
garage forecourt and it doesn't clean the grease, crud and dried insects off
the windscreen anywhere near as well and it leaves it streaky. I really must
get some concentrated screenwash and added it to the tank...

I can't imagine that a bit of alcohol in screenwash can cause goo that would
clog up the washer pump etc.

I don't give it a second thought. I have enough self-confidence not to
feel the need to hide behind a lump of metal.
