Sometimes I which I could transport some out-of-band data in the HTTP headers, such as some kind of "last changed" timestamp that I get from the database in some way. Currently functions return only a blob with the contents of the vector tile. What if they could alternatively return a ROW or something like that where extra columns are turned into HTTP headers?
In some cases this is not needed, you'll probably have an nginx or so in front anyway that can add headers. But if the data is coming from the database the reverse proxy will not have access to that.
