Potentially about anyone who used Access without the forms interfaces... While I'm not the biggest fan, I know a lot of people who prefer a visual editor for table schema creation. They'll use SQL Management Studio, or whatever equivalent with other DBMS and edit that way instead of DB specific queries... For example, re-ordering fields is destructive in a lot of DBMS and the queries get painful, a visual editor eases this burden.
As to importing/exporting data (csv, etc), You can't exactly run queries against a CSV generally (I mean you can with JET/ODBC, but still)... it's a chore.
To another point, I often feel that sqlite is a great backup format for data, it's portable, you can query directly, etc. I kind of wished that Azure Data Studio (now discontinued) had directly supported loading CSV/TXT etc into an in-memory or temp db for queries and portability similar to mentioned between various data sources (sqlite, mssql, pgsql, etc).
