Cons
Con Simple pages can hurt performance
A simple page can rack up on database queries. Many sites usually suffer from this. Create an empty page and there's a few queries that run and it's unneccessary.
Con Can be overkill for simple or smaller sites
Con Cost is high
Especially for commercial sites
Con Built on top of codeigniter: an outdated framework
Codeigniter was cool.... back when PHP was at 5.2
Con A lot of configuration
Example: a few plugins and some code are needed for gatsby-img or markdown to work.
