I am not an academic (in the traditional sense of the word as you’d think of it), nor am I a corporate researcher or a lawyer, etc. My use of DEVONthink - personal and professional - does not require me to cite sources nor does it (generally) require temporal filtering. I require no bibliographic information. My databases are full of various things for support purposes but personally, I write every day in DTPO (in Markdown 
) so I have many Markdown files. They have no “publication dates”. I have PDFs galore. Screencaptures. Media files. etc., etc. ad infinitum.
We have a very large academic User base. We also know that companion apps aren’t necessarily a bad thing. The old saw goes, If you have a hammer, everything looks like a nail. DEVONthink is more like a ratchet set - a simple function with options to fit different needs. A multi-tool (nor a Swiss army knife - though I love them and have had many in my life) does no job extremely well. It does them passably, but individual dedicated tools do a much better job. We don’t want to be the multi-tool that does everything “okay”. To this end, we listen and consider suggestions and criticisms, but we also need to maintain focus on what DEVONthink is ideally suited for.
Here’s an example: You can certainly file your images in DEVONthink, but people imagine it will be like a DAM (digital asset management) application. It won’t be. Apps like Portfolio or even Adobe Bridge (which is now free but slowwww) are made for this and have things like metadata capturing / filtering / etc. So it’s not that you can’t put pictures in DEVONthink. It’s just that it’s going to be similar to keeping them in a Finder folder.
I hope that makes sense.
