<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Perhaps. ecm is different because the maintainer/author of the Find modules is not the one using it, which is generally the case for third party find modules.
Anyway, the cmake-shipped Find-modules also use AUTHOR_WARNING. So, there's precedent, whether it's the right or wrong thing to do.
