even just extracting the apk's and side loading then is good enough for 95% my use cases. there are show that key you extract, but you would still want something that is trustworthy though. tasker is what I've been using lately and you can automate the process a bit more.
i turned off auto updates in the play store years ago after i got stuck with an app that had some bug in it, where it was working fine before the update. now i only update and app if something is broken or if i really need the new features it offers.
