So have it disabled by default, or avoid servers that use it, but speaking hypothetically there's no reason to eliminate it entirely even for people who want to opt in to it. I understand that EE2 hasn't been updated past 1.2.5 anyway, so that's another issue.
I run a very small server for a handful of friends who I trust not to abuse the power. I'd love to move to Tekkit Lite, but for the moment a large part of the way we play the game simply isn't there. Technical issues aside, that's a problem. If it was disabled by default and I could go in as an admin and say "Allow Condensers," it would be fine.** Mods like this are about enabling more to be possible, not less. Who are you to dictate what should and shouldn't be possible on my server?
**I understand that, at this moment, condensers are unavailable because EE2 isn't updated and EE3 doesn't have any functional equivalent. This is more of a hypothetical argument about whether condensers should be gone entirely.
