I don't know. some stuff has gotten less. Major databases now ship effective HA tooling, microservices seem on their way out, structured databases seem to be back in instead of NoSQL.

HTML and pre-rendering are back in, HTMx, liveview

The degaussing of CSS and the hacks we did, hell i was trying to explain how we debugged web pages in IE6 to a younger staff member today.

Some things are more complex, some things got good enough to make them less complex.
