Chromium based browser for armeabi-v7a

Chromium... I'm so getting downvoted with this one.

Anyways,

I have an old Android 6 phone that is still not completely unusable and my older family members want to use it as a backup phone (in fact, they already do). They can't live without Facebook (obviously) so I installed Firefox on it and made a PWA for Facebook. It works surprisingly well but Firefox itself is quite sluggish and slow to open on that piece of hardware. So I'm thinking of installng a Chromium browser on it, as well as on my other old devices to make them run a bit better and just out of my extremely unhealthy curiosity.

But the problem is they all do not support modern arm64 apps that most Android phones use nowadays. Instead they need this other type called armeabi-v7a. There were Chromium based browsers that had a v7a version (Bromite for example) but they all suspiciously died at the same time more than a year ago. Does Chromium really not support the old architecture (or whatever it is) anymore or I'm just not searching well enough?

P. S. Advices to buy a newer device will not be accepted and will be treated with appropriate level of hostility.
