why are all these flattenhtml="true" and allowexternalscript="true" needed?

Removed.

so preprocess="true" is required for <if> and <include>

flattenhtml="true" inlines things magically like <script src="..."> and url() in
CSS

are you sure you're not breaking some of these things?

they all have a specific purpose, but people just copy them without understand
them often :(

There's no docs for what the various parameters mean, and the grit
implementation doesn't make it super clear either :(
