Was this ever allowed? (Maybe a poor choice of words. It was obviously "allowed" 19 years ago by the AHJ.

no, if you look at the label on the panel it will tell the number and size of the conductors allowed in that lug and the other ground bars in the panel. Make sure you look at it correctly most allow only one grounded conductor but do allow multiple grounding conductors.

That label shows that 1 #6 up to 1 2/0 are allowed no multiple conductors and no conductors smaller thal #6.

Common practice years ago to twist all branch circuit grounds and go for one termination.

The SEP installed when my house was built in 1982 was done that way. I had the SEP replaced last fall and the electrician corrected all the 'old ways' and did it right (at least to current standards).

Making sure that no one thinks that was right back then, so I am pointing this part out:

... and the electrician corrected all the 'old ways' and did it right ...

I.e., the old way was "common", but it was also "never the right way".
