Updating to php 8 while on the master branch prevents the LTI connection from working

[spakula]

On our Moodle setup we've recently updated php to 8.0 (and Moodle to 4.3), and the existing LTI connection(s) from Blackboard through this plugin went "wrong": Blackboard users clicking on their appropriate "Moodle" item in Blackboard were shown a php error, and subsequently Moodle login screen, instead of the appropriate Moodle course.

The error message was: Exception - Call to undefined function get_magic_quotes_gpc()

I updated the plugin to 'Update-to-use-LTI-Advantage' branch (where the offending part of ims-blti/OAuth.php was removed) and the existing connection(s) seem to work fine now - but as an external "amateur" user I am not sure nothing else will break using a "not-yet-released, not even on the master branch" code.
