For me, its worth it, because the effort I spend to manually dep-clean use flags I don't need at present is far higher than any automated cost of rebuild will burn me. I've even recently started using `--with-bdeps n` in conjunction with --depclean ( because tip, depclean implies --with-bdeps y ), because I don't mind the rebuild cost, and I much more mind the significant dependency graph I have sitting around there not earning its weight. And the beauty of this is you woudn't pay a cent in terms of unwanted behaviour from the introduction of this feature unless you explicitly used it. You'd have to be intentionally using the lazy-use flags to see the undesired rebuild effect, and if that bothers you, its easy to just transition a soft-use into a hard use, just like if you don't like how depclean nukes a package, you can add it to your world file. -- Kent KENTNL - https://metacpan.org/author/KENTNL
