Yes, xRename was a part of the v1 module interface, but v1 module interface is not the first verson of it. Old sqlite extensions does not even contain xRename in their VT implementations and xFindFunction was the last one considered.
I understand what you mean by binary incompatibility, but it is not a reason to keep this issue unresolved. Without possibility to custom handling of collation in xBestIndex function is this great idea limited to be used only in case of numeric queries. Now it is no way to return correct results from VT using xBestIndex. Yes, I can keep these constraints on SQLite, but then perhaps these constraints should be filtered out from xBestIndex consideration. Perhaps new function returning CollSeq array for constraint structure in API could resolve it - as I suggested in previous post. It can be resolved even with binary compatibility.
