Problem is, it requires parsing the CREATE command looking for comments in a certain format. Notoriously difficult, considering that they can contain CR, LF, tab, and unforeseen Unicode characters. I’m utterly against anything that tries to read C-style comments. Comments are comments. Computers are meant to ignore them to the point that they don’t even know they exist. On the other hand, if we establish a standard for storing comments in database tables — which would require a consistent table name, column names, and values — it might take too much extra time to show those comments as an extra column in the response to PRAGMA tale_info() and similar PRAGMAs. But I think it’s overkill. Anyone who would want that would know how to retrieve the information.
