Is the "ESSENTIAL" attribute really appropriate?

Problem description

Hello.
In a misguided attempt to fix a problem I tried installing glibc-repo (through termux's normal pkg command).

I later ran pkg upgrade and it told me to install a slew of *-glibc packages.

I unfortunately accepted to do so, and found my device's storage full (yes, I had little free space).

That was my fault, but when then I tried uninstalling those packages, I found myself entrenched in "Removing essential system-critical packages is not permitted" apt errors.

After a while, I found out the apt --allow-remove-essential flag, I recovered the list of glibc packages from apt's logs, and after a safety backup I managed to uninstall them all.

First of all, this aspect should probably be described in the glibc-packages documentation.

Second, is it really appropriate to set TERMUX_PKG_ESSENTIAL=true to so many packages (15), or to any at all?
Or it was maybe only included by accident when making their installation scripts?

Finally, I did not actually break anything by forcing their uninstallation, right?
