I believe that's the entire point of this blog post. I'm rather puzzled to see the negative attention it has received.
Is this a huge pain point? No, but it is a constant niggling annoyance when using SQLite to power things like desktop apps.
If not built in to the core, I believe that SQLite supports compile-time extensions, would someone more knowledgeable comment?
I wonder if the OP would be satisfied with one of those? I personally would be fine building my own SQLite to get the functionality and it looks like the author would as well.
In short, I'm kind of confused as to why everybody seems so down on this idea. If an extension could be developed to do this, and if this extension would meet the OP's needs, I'm not sure why we're all going on about how it would ruin the sanctity and tininess of core SQLite. I'll put my $200 pledge here.
