Recent dating of Columbo series.

Recently, the dating for Columbo was extended to included an end-date to the series in 2003, the date of the last television movie.  I see from other threads that it has been a matter of debate where the series should officially end, but I want to register my complaint that I believe it to have been concluded on the wrong side.  Although streaming platforms are retconning (if you will) the television movies that came out between 1989-2003 as eighth, ninth, and tenth seasons, of course, this was not how they were perceived when they were aired.  They were television movies.  I think that IMDb ought to be faithful to the generic intention of the creators at the time of release rather than to a new perception after the elapse of two decades.  And thus the series should end in 1978.  

(I added much of this post to an existing thread, but I decided to make my own post to see if it might get seen.)
