Not for everything. For example, text/message/object box edition 

currently happens with the kind of interface you're describing.

Because Pd has no specification for GUI behavior, I chose to do a 

"primitive for primitive" port from tcl/tk to nw.js and only incrementally 

change some of the primitives to what you're calling somewhat more 

high-level, and only in those cases where performance dictated it to 

be necessary.
