There's no point complaining about what you think ebay should do. You pay fees to use the site as they provide it, not how you'd like it to be. They can't implement every little change or every feature that people want. I think it's fair enough that they actually allow us to change our handling time and we can't expect ebay to do everything for us.
Some people wouldn't want their handling times changed when they set their store to away, or they might want to change some items and not others, so to satisfy everyone it could get quite complicated, and that's when glitches happen. If your settings failed to revert back to how they were previously when you set your store back to normal you'd end up far worse off than having to manually edit a handful of postage policies. Ebay need to keep things as simple as possible and that's what they've done.
Lots of websites disappear from view if you set them to holiday mode and just because a few don't doesn't mean that ebay should be set up that way.
If you have any sort of business online you have to expect to do a certain amount of work when you go away, whether it's for a holiday or an emergency, just as someone with a b&m shop has to take a few moments to turn off the lights and lock the door as they leave. I think it would be a good idea for all sellers to have a back-up person who can change basic settings if they have an emergency and can't do it themselves.
