My first employer is now a decently well known B2B SaaS and we didn't build user interfaces to manage various settings for a very long time. For example, we supported custom fonts, but we would have to jack into production to upload them and manually configure the database to make them available to a given customer. That ability didn't become customer-facing for a decade, simply because it was easier to file a ticket and make an SRE do it.

This is a little tangential but another good piece of advice is to avoid over optimization of the engineering stack. A giant monolith running on the largest RDS instance AWS provides a lot more runway than people realize.
