MAIN, Uncompressed?

It looks like we need a new Column Storage option for MAIN, Uncompressed.

We have these Column Storage options
Plain - inline only, uncompressed
Main - inline until external as last resort, compressible
External - external, uncompressed
Extended - external, compressible

So there is no option for Main, but not compressible...

With reference to code... there seems to be no way to skip step 3

/* ----------
* Compress and/or save external until data fits into target length
*
* 1: Inline compress attributes with attstorage 'x', and store very
* large attributes with attstorage 'x' or 'e' external immediately
* 2: Store attributes with attstorage 'x' or 'e' external
* 3: Inline compress attributes with attstorage 'm'
* 4: Store attributes with attstorage 'm' external
* ----------
*/

Not sure what to call this new option? MAINU?

Objections?
