That's a fair (and understandable) ruling (even though it doesn't help me ;_;). On the 28 seconds - they're picked quite well. It's short enough that reasonable usage for non-R/D isn't affected, and long enough that R/D is affected, from what I can tell from playing the past year and change.
Option 1 is good for most purposes, though it falls short when it gets hot and heavy during update. Option 2 is something I might write up, though it's probably difficult to make a case for it beyond "helps defenders". Option 3 - I think I'll leave that alone for now, per your recommendation. Especially since you're surely looking much closer at any User-Agent with the name "Roavin" in it now
Thanks for your patience! I'll stop being insufferable now.
