Hi,
Thanks for the interesting infos, actually I've stopped with Unity Editor 2019.2.x series and also I've focused on pure coding studies (custom libraries developing) so many things got out of my sight (in particular I'm waiting for more updates to 2019.3,x series since I 've read is still too buggy to try porting all works of mine to that series).
By the way I can confirm you that with an Intel HD3000 series (mesa 20.2, OpenGL 3.3 profile) HDRP is not fully usable because of a particular shader type ("procedural shader" or something like that) that's not fully supported (even if it was in older Unity Engine versions, 5.x series If I remember correctly).
But, of course we are free to use whichever technologies we want in our works.
By the way, if I were you, I would use URP pipeline for games with stylized graphics, and HDRP for more realistic works.
Thanks again for your interest!
