if you've made it to 10 years, that's a really nice problem to have (or maybe a really boring problem to have). But if you're just starting out, I want to prevent you from making all those decisions when you could really be focusing on your startup instead.
So I'm trying to encourage you to consider picking a platform and just sticking with the tools of the platform rather than bundling it yourself together.
Or like how atlassian suddenly started charging a "serverless event" fee for their various workflow automation tasks a couple years ago basically slapping a $5-$10k markup on a product you already own. Thats just for small companies I'm sure there are enterprise customers that are paying six figures for a previously free feature and shrug it off. Like you said a good problem to have.
