One can also make the argument that if the user's clipboard is able to =
be read/modified, then their working environment is already compromised =
and that the responsibility is already not upon specific application =
software, but the user or OS.
Down here in the real world, an application that does not support =
copying and pasting of addresses is not an application that is very =
useful (to say the least) to many people who want to manage their own =
wallet, though I understand your desire to avoid such. Perhaps offering =
alternatives such as supporting signed BIP70 payment requests is what =
you mean to do.
That said, I still think working around specific malware threats and =
vectors isn't the application's job, especially when doing so for a =
tiny, tiny fraction of users that have malware outweighs the needs of =
the 95%+ that need to support the "I have an address on my clipboard I =
need to pay" case.
Best,
