I can't claim to be a security expert any more (I've drifted away from
that topic over the last decade or so), but most data breaches that were
publicised over the last few years started at some employees desktop.
As such your assumption "server A may be hacked, server B safer, and the
application is completely safe" seems unrealistic to me. I think that
the application will fall first (and whatever privileges it provides to
the user will therefore be in the hands of the attacker), and the
server(s) will come aftet that. So I would design such an application
with the assumption that the user's PC has been compromised and secure
the server(s) against that case.
