Installation without composer

[cngJo]

This extension cannot be installed without composer currently.
We rely on some composer packages, which are not part of TYPO3 itself.

Is it possible to run composer install when creating a release and include the vendor directory in the ZIP-Archive Github generates for the release?
Also: I guess we need to adjust dependency loading.

Is this even worth it? How many TYPO3 installations nowadays do not use composer?

EDIT
It seems like there is a pretty easy way with composer to accomplish this.
Example from EXT:solr: TYPO3's EXT:solr does this: https://github.com/TYPO3-Solr/ext-solr/blob/main/Resources/Private/Php/ComposerLibraries/composer.json

Not implementing this, most of the installations use composer nowadays so this "feature" is not needed.
