Obtainium vs Aurora Store for Updates

I have both Obtainium and the Aurora Store installed on my GOS phone (as well as F-Droid and Accrescent). The Aurora store will notify me for updates that aren’t available yet on Obtainium. For example, currently I have ProtonMail version 7.9.5 installed via the Aurora Store, but Obtainium says that 7.9.4 is the latest version. I’ve seen this with other apps too. I think that this means that some app developers aren’t releasing their source code to GitHub, GitLab, etc. as quickly as they’re releasing their apps to the Google Play Store. It kinda bugs me that developers aren’t releasing their latest source code as they publish their apps. The code that they check into git should be ahead of their releases, not behind. Not much I can do about it though. I like the idea of installing directly from the source (or as close as I can get without compiling it myself), but I’m starting to think that I should just use the Aurora Store for everything. It gives me access to all apps in the Play Store, which is pretty much everything, and gives me the latest version. I could reduce the apps on my phone by getting rid of the other app stores that I use. I’m curious what others think about this idea.
