Making it harder to program is not synonymous with making the programmer 'more aware'. I'd argue the opposite. It's much harder to figure out the source of or find all references of something without an IDE. An IDE with intellisense makes the programmer much more aware of what his/her options and navigate large code bases quickly.

String searching text files for definitions or references is just crude.

When Javascript became ubiquitous.
