Remove the default 72 PPI resolution
There is NO device on Earth (except in museums) that have 72 PPI screen.
However, EVERY new screen-intended document created today in Illustrator and Photoshop STILL made with only 72 PPI by default.
With this laughable resolution, all raster effects are rendered, looking just bad on any screen.
Since 72 PPI is the actual World Standard, it confuses many Adobe users and it has to be changed for good.
Today's computer screens have at the very least 120 PPI, but the phones for which many projects are created have a way higher pixel density of 450 PPI and more. The 72 thing is irrelevant for years.
This is really embarrassing to see beautiful clean vector artwork being rasterized with such low a resolution, and this is annoying to change it manually for each and every screen document.
Please, correct this, pick an appropriate contemporary default, make it the New World Standard.

If you're talking about raster effects, then I think the specific feature you're asking for might be a custom field in 'Document Raster Effect settings'.

At least, the label "Screen" should be changed to "Low".
Nowadays it reads:
High 300 PPI
Medium 150 PPI
Screen 72 PPI
My students are laughing since the least advanced phone in the class has a much higher screen resolution.

Illustrator also uses 72ppi when setting the pixel bounding box size within SVG files, so when importing its SVG output into another (modern) program, the SVG appears at 3/4 the size you created it! Adobe's attitude to this is that Illustrator has been around for 30 years, it's always been 72 dpi, so they can't change it [lies]. Adobe would rather ignore the 96ppi CSS standard than do any work to fix their archaic software.
