Yes, st follows terminfo(5). Every terminal has different keys,
so, I don't know what you mean with st using different keys.
You can see the differences between xterm an linux vt:

If your program does not use terminfo(3)
(http://linux.die.net/man/3/setupterm), then is broken.
About the problems with DELETE, please take a look to
the FAQ (section Why doesn't the Del key work in some programs?)
