The Stupefied condition says

Your thoughts and instincts are clouded. Stupefied always includes a value. You take a status penalty equal to this value on Intelligence-, Wisdom-, and Charisma-based checks and DCs, including Will saving throws, spell attack modifiers, spell DCs, and skill checks that use these attribute modifiers. Any time you attempt to Cast a Spell while stupefied, the spell is disrupted unless you succeed at a flat check with a DC equal to 5 + your stupefied value.

The first half of the Stupefied Condition gives a penalty to Int, Wis, and Cha in much the same way that Enfeebled and Clumsy give a penalty Str and Dex, respectively. Just a flat penalty to Checks and DCs.

The second half specifies that any attempt to Cast a Spell needs to make a flat check or waste the attempt.

Then under Impulses it states that

Impulses are magical, and though they aren't spells, some things that affect spells also affect impulses. Abilities that restrict you from casting spells [...] also apply to impulses.

So, repeating the title - are Kineticists affected by Stupefied, given that although Impulses are not spells (nor Int-/Wis-/Cha-based, for that matter) they are nonetheless affected by things that prevent spells?

Recently I've realized that almost none of the Impulses have the Attack or Manipulate trait, meaning that Restrained is little different from Grabbed, when used against a Kineticist.

For all other classes Restrained is utterly crippling - martials can't even Strike and spellcasters can't cast spells. Until they Escape. And even on a success, the Martials still suffer from MAP and lose an Action whereas spellcasters are rather unlikely to ever Escape at all (assuming it's not a lower-level enemy).

Yet Kineticists don't really care. They can use most of their abilities unchallenged. Is this intentional? Am I missing something obvious?
