HypeWall plus Elgg 3x

I am unable to install hypewall (current github version) with Elgg 3x latest RC. The installation gives error and the admin panel gets lost. To get back the admin panel one has to delete the plugin folder (php 7.3). There being no other proper alternative to hypewall (unless it gets into core immediately) I am wondering will Ismyl return on earnest request or will anyone release 3x compatible versions. What will the sites using hypewall in Elgg2x do when they upgrade to Elgg3x.?
