I thought that one of these caught the contexts of the ASA:

cisco;command;ios::WriteTerm;more system:running-config;ASA/PIX
cisco;command;ios::WriteTerm;show running-config view full;workaround for role-based CLI

Others have used separate router.db entries for each context on the PIX.

And, the a10 has some similar configuration that is apparently (I do not
have one and am not familiar with it) not dumped with the rest of the
config.  To collect that, a10login had some weird stuff, which was buggy,
that attempt to parse the output from one of the commands in the command
list for a10 and insert other commands into the output.

To do that more generically - and not in tcl, i started adding a way to
insert commands.  eg:

 a10;command;acos::ShowAflex;show aflex all-partitions
+a10;precommand;acos::AflexCmds;show aflex;#requires the command above
 a10;command;acos::ShowRunningConfig;show running-config all-partitions

rancid would run the precommand(s), which could insert commands into
the command list or a postcommand list to collect output for each of
the configured partitions.  It does mean multiple logins, but feh.

Is this appealing for the ASA (another platform I have little experience
with) problem?
