Looking at the size increase, the v5.6 -> 5.9 increased way more than
5.4 -> 5.6. However this is also true for the ll config (and is not
limited to RT):

rpi3-image-ll-v5.4.59-rt36 -> rpi3-image-ll-v5.6.19-rt12 -> rpi3-image-ll-v5.9-rc2-rt1
0                          -> + 1.1 MiB (4.2%)           -> + 3.1 MiB (11.2%)

rpi3-image-rt-v5.4.59-rt36 -> rpi3-image-rt-v5.6.19-rt12 -> rpi3-image-rt-v5.9-rc2-rt1
0                          -> + 1.0 MiB (3.3%)           -> + 4.6 MiB (14.3%)
