'Simplification' of 夠 Why did 夠 get 'simplified' into 够?

I'd like to know whether these existed as orthographic variants before simplification (such that the first round simplifications just standardised on one variant) or if there was some other basis, perhaps ideological, for either choosing one of the two forms, or creating a new form with 多 on the RHS.
This is discussed extensively in this thread:

A quote


  Because the "simplified" version of this character was made PRC
  standard when the new character lists were published. Even though
  nothing was actually simplified. There was a committee in China tasked
  with simplifying and standardizing written Chinese, when they came
  across this character they noticed there were two common versions of
  the hanzi being used so they had to pick which one will be in the
  official government approved lists. 够 won out.
