I voted against.  A decision to deviate from the norm with something as important as a runtime should be undertaken with sufficient notice to stakeholders and perhaps testing with this intent in mind.  

Well motion 363 has now passed, so maybe this poll should be about future runtimes.

What are the implications, i.e. why is the compressed one not used all the time?

When the WASM runtime is built, both a compressed and a non compressed version are built.
Until now, the non compressed version has been used. 
The compressed version saves >73% in runtime size: 0.956 MB vs 3.582 MB
The compressed version of the runtime is already on Westend for >5d.

#981 Should Kusama Runtime 9100 be using the COMPRESSED Runtime ?
