Description

For a rarely used feature the overhead is really too big -- making up 7% of our response times -- and it's all spent in the regex engine.

GetLiteralTokens bench

Could this be placed behind a flag or in a DynamicParameters derived type?

If so I'm willing to PR it.

Research direction

No file or test is named. Start by locating GetLiteralTokens and profiling the regex-engine path for large command texts. Done means agreeing on whether the work belongs behind a flag or in a DynamicParameters-derived type, then demonstrating that the reported overhead is reduced.
