Well, except for the webserver with nginx or apache, correctly configured with SSIs enabled. It's not terrible -- but not 'obviously' less complex than using e.g. 11ty (a static site generator) + uploading to an s3 bucket or FTP server. Just trading off complexity in one place for complexity in another. A sibling (top-level) comment suggest a standard HTML templating (or SSI) language that many static hosts would support. I like that idea quite a bit conceptually, though of course much easier said than done.
