It makes me a bit disappointed, that it's still not possible to make a self hosted setup without 1 gig of disk.

Let's say you have an old seedphrase backup, and want to load it in a new setup to check the balance, in own bitcoin core node + electrum + sparrow stack.

Bitcoin core will download all the blocks!

With assumevalid, it will not _validate_ most of the old blocks, but it downloads them.

Pruned you cannot set until first you download everything.

Electrum does not work with pruned node.

So you need 1 gig of disk space and a few days to do this...

AFAIK there is no shortcut that does not rely on external server or some other trick (like copying blocks from another pruned node).
