Thanks!

Because there are perfectly good ICE for it.

JTAg is run control, Flash programming and board test. It is not an
Emulator.

It requires a JTAG block and debug block on the silicon. this tames
space and power. It also costs to implement

On a small 8 bit system there is no gain on having a JTAG unless it is
going in an ASIC or FPGA

The JTagICE needs a JTAG port.  The ATMega8 does not have a JTAG port.

Not enough pins.
If you need this functionality for development, use a mega16 on th eprototype
and switch to mega8 on
production boards.
