Compact Number Formatting and Fraction Digits

I'd like to have 1 fractional digit unless it's 0:

1,000 -> 1K (*not* 1.0K)
1,500 -> 1.5K

I think that is not even expected when min fraction digits is set, but considering the objective of compact number formatting this could be a good value add to introduce an API which if set, truncates trailing fractional zeros while formatting output. This may need some thought process on its feasibility.
