Note: only 42033 (Clear Read-Only Flag) but not 42028 (Set Read-Only) entries are removed from the localization files.
Because 42028 (Set Read-Only) command is only reworded, its functionnality remains the same.
Whereas 42033 (Clear Read-Only Flag) command has changed its behaviour, hence the deletion.
