Hello,
Although Electrum clients connect to several servers in order to fetch
block headers, they typically request address balances and address
histories from a single server. This means that the chosen server knows
that a given set of addresses belong to the same wallet. That is true
even if
I should add that the obvious resolution to this set of problems is to
use a distinct Tor route for each Bitcoin address, not to reinvent Tor
and reproduce its community. So ultimately this is easy to implement,
but the downside is performance.
But it's important to keep in mind that
One solution would be for the client to combine all the addresses they are
interested in into a single bloom filter and send that to the server.

Hey Joseph,
All those ideas are ones we had years ago and they are implemented in the
current Bitcoin protocol.
The trick, as
I would recommend the following solution as a decent compromise between
complexity and privacy:
1) Encourage electrum server operators to have their servers reachable as
tor hidden services (.onion addresses)
2) Make sure server discovery works well with .onion addresses
3) Make the privacy a
