Expanded Selection for SNA / SM

[Evershifter]

Has anyone seen or heard of plans to release any updated charts for Summon Monster or Summon Natures Ally as Paizo continues to release new monster books? I understand that these are both fairly strong spells already, but adding to the available monsters seems like a reasonable request.

If not, anyone worked out a formula for figuring out what power level would be appropriate for house-ruling added baddies?

New monsters will not be added.

Basically, existing spells will not be expanded. but new spells would be created.
Edit: Linked to a more recent post.

The Planar Binding/Ally spells are less restricted than the Summon Monster Spells, so you might look to those if you want more options.

Wasn't there a thread about the same topic just two days ago?

EDIT: sorry, that was about expending availability for possible animals as ACs.
