You are choosing one branch of the Linux family tree over the other. Alienating hundreds of other Linux distros by giving preferential treatment of Debian based ones over the others.
For example when you enter the enterprise landscape you may find that there are more RHEL based distros. Than Debian based ones that are being used.
When you decide to go down the Debian path you have to consider the dependency hell you are signing up for too. When there are major version releases of Debian, or Ubuntu based distros your dependencies will always be out of sync with each other. Debian will always be behind and ubuntu will be ahead. Leaving your users up shits creek to paddle themselves out of the mess.
In the Linux world there is a shift towards a more universal package management approach. With flatpaks, appimages, and snaps being the preferred choice for Linux package management and distribution. This is, because by bundling the dependencies with the application and maintaining them in this method. You do not have to worry about the dependency hell.
With flatpaks you make one package that will work with every Linux distribution. Easily updated and maintained gracefully. You can use debs if you want, but when you ultimately experience the headaches later. Remember there are better more up to date solutions that can better the Linux community as a whole. Not just one biased branch of the family tree that is slowly becoming obsolete.
