I think developers underestimate the ecosystem and community aspects. Software is definitely not a space where "if you build it, they will come". There is better codebases, but no one has held a candle to the ecosystem yet. I believe this is because the core users of WP are not it's developers, the users (admins, agency clients etc) hold a considerably larger stake in typical business engagements.

I have been doing eComm agency work for years and even if the chosen eComm platform does have a CMS, we're very often asked to integrate a wordpress site for the company's marketing/content team to use.
