Yes, they are. The reason for this is that ISL was a proprietary solution. Now that .1q has become the standard, all new products will operate according to the standard. So you should indeed be careful in selecting & implementing new equipment in an ISL-based environment.
When it is Cisco's intention to keep supporting ISL I cannot understand why it is not supported on the 2950. This is the recommended replacement for the 3500 series but it lacks this vital feature. You guys at Cisco must have caused headaches for quite some folks who forgot to check all related docs.
The mentioned "hardware limitations" will have been enforced by your marketing deparment I suppose?
In my opinion ISL was the better solution. At least, it is easier to understand how it operates and you do not need to worry about native vlans.
