about pdf/a... until recently there was not even an easy way to figure out if pdf is really pdf/a; now there is (verapdf) and it's crazy complex piece of software

and maybe I'm wrong but the only way to convert arbitrary pdf to pdf/a with open source software is to convert it to postscript and back with ghostscript - which is affero licensed... with all the possible problems it entails. (there is old version that is just gpl, works on most pdfs but is 15 years old or such.)

i needed to deal with pdf/a in a previous job... was not fun.

And what problems are those? Besides making it harder to leech off the community without giving back of course.

You could use the pdfium library as an alternative to Ghostscript.

I don't think there is a way to do that with pdfium. I have tried to look at it and failed. Maybe I didn't look hard enough.
