I'm not arguing for arbitrary changes, but if the change makes sense and isn't trivial it should be done. What is needed is to tweak the tools for such a move- specifically adding a new command to the update machinery (profiles/updates). Something roughly like usemove [atom] original_flag new_flag If an atom is specified, the move applies only to w/in that pkg; if no atom, it's a global shift in the configuration (meaning all ebuilds now use gtk instead of gtk2 for example). Examples: usemove gtk gtk2 usemove app-admin/gtkrellm gnutls ssl usemove dev-cpp/sptk:3 gnutls ssl usemove >=app-editors/emacs-22.3 gzip-el gzip Etc. Per the norm for updates, usual rules apply- since it's a string of delta commands, once a command is in there it cannot be changed in purpose (although folk can tweak existing commands to update for a final target, eg: A -> B, B -> C; changing it to A -> C, B -> C). > Also two little side points...

USE_EXPAND, roughly- I wouldn't say it's fully there, but it certainly would be where I'd start for any proposal... ~harring
