Sorry, but choice of language means more than nothing. ColdFusion is pretty dead-end and not a particularly good choice these days for a variety of reasons.
If it works, and you can maintain it - its all good. Even Cold Fusion, even PHP, even Perl, even Brainf#@k
The consequences come for the poor bastards that have that old crap on their resume... Bus number notwithstanding...
Not that I disagree with you, but I wonder if the reasons you have in mind are valid. A lot of the reasons one might assume CF sucks aren't really applicable (i.e. speed, security) any more than most other languages.
