Research direction
Start at proxy-plugin.c:2086 in proxy_read_query and inspect how the shown SET SESSION sql_mode query is classified as Syntax Forbid. Reproduce the reported query if the repository provides a relevant entry point; done means this session-level REPLACE expression is accepted without the reported warning.
