Which CI-Class for Desktop Software if not Business Application?

[Manu15]

Dear Experts,

I am a bit confused which CI class is the right choice for mapping locally installed fat client applications. Some of these applications are referenced in business processes, some are just Tools like Notepad++ or other common used tools.
We use Enterprise Architecture / SAM Pro and have mapped locally installed applications on notebooks as Business Application.
I have read some community articles on the subject, such as What is a Business Application?  by @mcastoe, and since then I have doubted our previous approach. I also had some appointments with local ServiceNow consultants who told me that our approach is the wrong way (which would be logical due to the selectable architecture types) and that we should customize a separate CI class for such locally installed fat client applications, which references the product samp_sw_product and the installations cmdb_sam_sw_install.
Isn't there a more elegant way? We would like to follow the ServiceNow standard as closely as possible and use the functions that SAM Pro and Enterprise Architecture offer us in terms of lifecycle management. I saw the CI class Desktop Software cmdb_ci_desktop_software, but it seems to be a bit legacy and not really SAM integrated.
Which CI class is the best solution for mapping applications installed locally on notebooks that do not use any infrastructure (servers, databases, etc.)? I seem to remember that in earlier releases of APM, fat client applications such as Adobe Reader were also mapped as business applications in the APM demo data. Now I no longer see these applications in the demo data. Has the definition of a business application changed here on the part of ServiceNow?
