It depends of course on what the required platform is. If it is the
"mainstream" platform, AT is likely to be available for it.

If you consider a longer perspective it is never good to lock yourself
to a specific platform. Let's say that a year from now the
IT-department finds a business case for switching to Linux. If tools
rely on a specific browser this may make the transition a lot more
difficult. Although that is not an accessibility issue.

browser B I guess there would be problems.

The Swedish government also did an evaluation of CMS:es inspired by
ATAG (1) but the platform independence was of less importance than
other criteria.
