Yes, actually. Academically marketing is defined by the general marketing mix of: Product, Pricing, Place, and Promotion. Product here relates to fully understanding the end users goals. You then need to design a product that meets those goals, and a brand which communicates to your user how those goals are met.

It's common place now for people to think of 'marketing' as 'advertising'. It is a much more robust subject than that. This is driven largely by the product management role being so closely integrated to the engineering flow. As I understand it, traditionally product management was a marketing department role. You can see this more with non-software companies like food or transportation.

Interesting TIL. Definitely not how I perceive marketing though. I always saw it encompassing promotion and brand.

I'd say it is more accurate to characterize your points as a "marketing feasibility analysis". But this is as much my opinion based on my understanding of marketing, as it is actual "marketing of a product" per se.
