It is not a software compatibility issue.  Basically *All* of the software 
that that is used on 32-bit Raspberry Pis runs on the 64-bit Raspberry Pis. 

You are thinking like a "PC" user. Raspberry Pis are not "PC"s. While they can
(and are) used as "desktop" (I am using a Pi5 as my main desktop machine) and
as "servers" (I am using a Pi2 as a print server -- note there is no reason to
not upgrade that machine to a 64-bit Pi3, it is just that I had the Pi2 lying
around and not otherwise being used and it works and is currently supported --
"If it ain't broke don't fix it."), but they can and are used for embeded
uses. *Sometimes* those embeded uses have contraints that preclude using newer
64-bit versions. I repeat: it is not a *software* issue. A 64-bit Pi would run
the software involved, but the newer 64-bit Pis tend to draw more power and
generate more heat. Pi 1's and Pi 2's never needed heat sinks or fans. Pi 3's
can be run without heat sinks and fans, but they do draw more power. Pi 4s and
5s really need heat sinks and fans. This is not a problem for desktop or
server use, when powered from the power mains and in situations where a fan
can be added without problems (eg plenty of space).

You have to understand that Raspberry Pis are not the sort of "black box" that 
x86/x86_64 computers effectively are.  Generally speaking, people who use 
x86-flavored "PCs" can and do treat these machines as interchangable.  People 
who use Raspberry Pis might have very specific and specialized use cases that 
depend on partitular models.  Sometimes the relevant specs are not in terms of 
performance, but things like thermal or power issues or circuit board size (eg 
Pi Zero).
