[opensysusers][libretools]: [REVERT] bcf93cb83 and ceabb79eb
    
    commits from bcf93cb83 to fbd84207c were WIP experiments
    including some that reverted important published changes
    none of those should have been published; but they were
    and abslibre is ff-only - so this commit undoes the reversions
    
    the other WIP commits in that range are not usable either;
    but they do move forward, so they may as well stay
