In languages like Ada that tend to need to be separately compiled for the
target OS, this is reasonable.

In languages that can portably run "anywhere", like Java in particular, some
sort of runtime query is needed, since the code is built once but executed in
multiple environments.

And then there is the case of ports of Ada to the JVM, so that Ada apps can in
fact run in multiple environments as well.
