Is it?
On the LPC2148 communication fails *just* above RCLK frequency.
Also, it is possible to redefine jtag_rclk (tcl procedure) in the interface
definition to do whatever you want.
openocd .... -c "proc jtag_rclk {a} {jtag_khz a}" ...
=> do not use rclk...
This is more how to formulate a target script such that it can give the
user control over what happens, but to have default behaviour
that matches >90% of all users.

I don't understand your question. There is no "default".
The target config scripts decides whether to use rclk or not.
