No, only current can change ->blocked. This is even documented in
sigprocmask(). And more, the only correct way to change ->blocked
is set_current_blocked(). OK, with a couple of "I know what I am
doing" exceptions in kernel/signal.c.

I was looking at force_sig_info() and derivatives.  Is that what you refer to?

If so, is it worth providing a force_sig_info_current(),
force_sigsegv_current() and force_sig_current() to make things clearer to grep
for, I wonder?
