Make Transaction Performance Monitoring Filter non-experimental

A potential customer is highly interested in using https://mariadb.com/kb/en/mariadb-maxscale-25-transaction-performance-monitoring-filter/ but this is currently (despite docs not stating this) experimental only, which means it cannot be safely used in production.

The customer's specific statement for their interest in TPM is-

there was a goal of plotting query timings and providing some insight into transactions and the TPM looked to accomplish some of these goals

Customer also asked if this will be available properly in v2.6 (v6), but I am not seeing any roadmap for this feature nor inclusion on v6 release notes.

Can we consider taking steps necessary to make this prod-ready and to release it in an upcoming MaxScale version? If not, are there fundamental problems with the filter as-is and can we make a new feature which would address customer demand for the problems the TPM filter solves?
