Thoughts?

I disagree. A slipping turn can be very useful.
They are not inherrently unsafe, unlike a skidding turn which is very
unsafe.

One could argue that coming out of a slipping turn is the same as
skidding momentarily. *The inside wing slows down and runs the risk of
stalling. *But I think we are getting caught up in the nuances. *I
also agree a bit of yarn works, if you are paying attention, but there
are a lot of things that may demand more attention in pattern. *Many
of them quite unpredictable. *People spin in. *That we can all agree
on. *Staying coordinated and fast enough would prevent it. *Hopefully
we can agree on that. *The question is, is there any value in another
indication that we are uncoordinated?

A simple implementation would be just two pressure ports on the sides
of the nose connected together with a reed noisemaker. *In a skid or
slip, the pressure difference would set off the reed reminding the
pilot to pay attention to business.

see youtube for multiple videos of pilots landing apparently
accidentally gear up with gear warning horns blaring...

"what is that noise?????"

Yes, bells and whistles only work if you are suspecting something is
wrong. There is that story of the pilot who just fixed his gear alarm,
and when the gear alarm went on the next time he flew, he noted to
himself 'great, the gear alarm is finally working' and proceeded to
land gear up...
Yaw alarm can only be useful if it will be triggered only when
skidding, not slipping, otherwise it will be ignored quickly due to
false alarms.
