There are such post-installation scripts, but it looks like they are not
working in Silverblue. This is something that needs to be addressed in
Silverblue.

32-bit vs. 64-bit is one example (which is why the directory names contain
the CPU architecture, e.g., x86_64).

This is how almost all software in Fedora is packaged: the main package
contains the files required at runtime, the -devel package the files
required to compile software against the package.
And the ambiguous naming is really upstream's fault, because there is no
such thing as "OpenJRE".

Modular Java programs do not need a full JDK either, a JRE is sufficient.
The full JDK is only needed to compile software from source.

This is supported by the alternatives setup. (It is the reason why there are
separate jre and jdk alternatives, though the latter tracks the former by
default, but you complained about exactly that complexity…) But what such
standalone JRE should Fedora ship? Again, there is no OpenJRE. We can only
ship the JRE subset of OpenJDK as the default JRE.
