sql.js size optimization

Not exactly a issue, more of a question/idea. I'm trying for a serverless application, and I need to run a few complex queries (tree-like and such). The data would be imported from another source on load time and there would be no need to maintain it, just query. In the end, I would need a sql.js that could:

• create tables (no need to alter/drop);
• insert data (no need to update/delete);
• run complex query on low volume data (few thousand lines at most - no need for views, but temp tables, indexes and subqueries needed).

Do you know if these are achievable on compile time? And would you consider making a sql.js version with such features? If possible, I imagine this could shrink the sql.js a lot.

The issue names no files, tests, or entry points. First determine whether sql.js/SQLite features can be excluded at compile time while retaining table creation, inserts, indexes, temporary tables, subqueries, and complex queries. Done would include a measured smaller build and confirmation that the requested operations still work.
