UnifiedNlp VS smart-referer

Hello, I'm trying to add microG to my OS by following the microG wiki (very well written!) However, I'm not able to add the additional patch(https://github.com/microg/UnifiedNlp/blob/master/patches/android_frameworks_base-N.patch) to make location work (mentioned here - https://github.com/microg/GmsCore/wiki/Installation)

https://github.com/microg/UnifiedNlp - acts as a middle ware for multiple backends which have network location features.

MicroG has a list of NLP modules. Afaik it doesn't harm having several installed and working concurrently. The list here: https://github.com/microg/UnifiedNlp

Get UnifiedNLP - essentially does Locations services but not google

Another option would be to use an other location provider than google, like unifiedNLP.

I assume you are talking about microG. I have no personal experience with this because I've always just installed Gapps, but I wasn't under the impression UnifiedNLP or similar required microG. The installation instructions for UnifiedNLP just talk about downloading a couple APKs, and maybe installing as system apps (https://github.com/microg/UnifiedNlp/blob/HEAD/README.md). I do see that the app itself is made by the microG project, but it does make the claim (in several places I've found while searching) that "most" ROMs support it. What am I missing?

Here's a link to more location backends, you can rule out 4 or 5 since some are old and others are for China.

Note that some sites depend on referrer and might break with this.

Here's a list of them maintained by the extension mentioned above: https://gitlab.com/smart-referrer/smart-referer/-/blob/gh-pa...

Now the problem is that it hasn't been updated since 3 years(last updated on Dec 18, 2019 according to AMO). Last commit on its gitlab repository was done on Sept 15, 2020. Now I am no developer, but I am sure that there has been quite a few changes in Firefox and some heavily discussed changes like MV3 and others are making its way to the browser as well. The add-on seems to have been abandoned by the developer judging by the activity in the repository.

Well there's a read me here that talks about whitelists etc. From a quick look it seems like you could probably accomplish the same thing with ClearURLs or similar. The default whitelist seems to be out of date by three years. Isn't this thing abandoned?

Smart referer (link, and I believe it is firefox only?)

If not, is there an option too? I saw this (GitLab - Smart Referrer) but I wasn't sure if it was necessary if Firefox and/or Brave already does this for me.

Smart Referrer Control -- Defer Referring information in a smart way

Source code is on gitlab

I would also recommend Smart Referrer and ETag Stoppa.
