If you need old versions, you should try CentOS or RHEL.Being leading edge doesn't mean those usecases aren't relevant, one is not mutually exclusive to the other, especially when it comes to things like FPGAs etc.
There shouldn't be a problem spinning up a graphical environment of CentOS 7, getting EPEL and then using the tool.
Maybe the tool would work using the `toolbox` utility using last known good Fedora version for the tool.
That is just my wild guess however.
This is sometimes the tax for being "too" modern.
If the vendor does not want to support Fedora, we can't be held accountable to fully support their solution.
Does the software work? Yes? That is great! If not, well… we can't do much without the source code under nice FOSS license, can we.Regards,

Although yes, there are things like VM's, containers etc. which we use for old development environments all of these are, IMO, clumsy and awkward to use and difficult to manage especially within automated build environments that build the complete code for an embedded system with various CPU's, FPGA's, other tools etc.
I know Fedora is fairly bleeding edge (really too bleeding edge for our uses, but others are too far behind), but there is obviously going to be a balance here so that Fedora is still useful to as many people as reasonably possible, hence the question on a policy.
In the particular case I am talking about, libncurses*5.so, this is a fairly common shared library used by quite a few command line tools. A lot of external/commercial programs are built on/for Redhat7 as it is a de-facto base Linux platform and programs built on it will likely work on many other Linux systems. These companies are not going to build for a version of Fedora, it changes far to fast and would require large amounts or development/support work because of this. Some of the tools I am using were built/shipped in Feburary 2022, so we are not talking about old tools here.
My view is that compat versions of the commonly used shared
libraries for programs that are used on Redhat7 should be kept
available until most people are not producing programs for that
system at least +nyears and then I guess Redhat8 once that really
becomes a core base platform that external people use. A core list
of these (there are only a few) could be kept somewhere and when
one is to be depreciated, or users see problems when Fedora is
updated, a decision on this can be then made with that info. This
would keep the Fedora system relevant for more users needs without
too much work. In the case of ncurses, it is really just putting
back into the SPEC file that which was removed for F37 plus the
extra storage on mirrors for the compat RPM's.
