[Bug]: pkg install gives Notice: Missing Signed-By in the sources.list(5) entry for 'https://termux.net'

[SwuduSusuwu]

Problem description

This is not about specific packages, but is about ~/../usr/etc/apt/sources.list.

What steps will reproduce the bug?

~ $ pkg install mingw
Hit:1 https://termux.net stable InRelease
All packages are up to date.
Notice: Missing Signed-By in the sources.list(5) entry for 'https://termux.net'
Notice: Consider migrating all sources.list(5) entries to the deb822 .sources format
Notice: The deb822 .sources format supports both embedded as well as external OpenPGP keys
Notice: See apt-secure(7) for best practices in configuring repository signing.

What is the expected behavior?

Due to the fact that Termux has ~/../usr/etc/apt/trusted.gpg.d/termux-packages.gpg, expected apt (pkg) to use those.
Since it does not, expected searches to show how to do so.

Searches through man pages, through GitHub discussions, and through Google have not shown how to do.
If it is not plausible for Termux to fix the defaults for this soon, want to know what to do
