No good reason. I'm more familiar with the other commands since I use
them often is the main reason. A side benefit is that I can match
existing tiles on other datasets and adopt existing tile names too. Now
that I've read the utility pages for gdal_merge and gdal_retile I see
that would be an
That is a surprise.
In all my tests I had no memory problems with gdal_retile. Sometimes I had
some memory problems with gdal_merge. The biggest input file for gdal_retile
was a 80 GB Erdas image (not compressed) and it works fine.
I have never testet with an ECW File and my tests run on a

I did some experiments reprojecting the single tiles while retiling, but
it simply does not work. As a consequence I canceled the reprojecting
support.
The solution for your problem is:

A short question
Why did you not use
1) gdal_merge
2) gdal_translate
3) gdal_retile
Btw, if there is no need for reprojection, gdal_retile alone does the job.
Did you have problems using these utilities ?
