Long story short, the A321XLR needs more development time than the A321LR.

For many of the steps there have been issues such as implementation of ACF. If they had all been implemented with the basic neo it would have faced many delays.

I noticed that compared to standard A321NEO there are not that many changes in its XLR variant and not to much of OEW difference between it and NEO with extra ACTs.
Wouldn't it be beneficial to introduce integrated rear fuel tank earlier?
What where the technological hurdles that had to be overcome so that it is only now that XLR is being worked on, and not already available with NEO or NEO LR introduction?

IMU they are creating a "siding" in the fuselage segment production around the integral tank.
probably not a dumb idea. the change is rather intrusive.
