Whenever I install a fresh smcp version 2.5 or upgrade from a previous version of smcp. The only stats envoyfilters that are created/remain are the 1.6 ones

NAME     READY   STATUS            PROFILES      VERSION   AGE
basic2   9/9     ComponentsReady   ["default"]   2.5.1     6m33s

NAME                               AGE
metadata-exchange-1.6-basic2       4m59s
stats-filter-1.6-basic2            5m1s
tcp-metadata-exchange-1.6-basic2   5m2s
tcp-stats-filter-1.6-basic2        5m

Then in 2.4 

cruhm@cruhm-thinkpadp16vgen1:~$ oc get smcp
NAME     READY   STATUS            PROFILES      VERSION   AGE
basic2   9/9     ComponentsReady   ["default"]   2.4.7     3m39s
cruhm@cruhm-thinkpadp16vgen1:~$ oc get envoyfilters
NAME                               AGE
metadata-exchange-1.6-basic2       2m50s
stats-filter-1.13-basic2           3m
stats-filter-1.14-basic2           2m59s
stats-filter-1.15-basic2           2m57s
stats-filter-1.16-basic2           2m56s
stats-filter-1.6-basic2            2m52s
tcp-metadata-exchange-1.6-basic2   2m53s
tcp-stats-filter-1.13-basic2       3m
tcp-stats-filter-1.14-basic2       2m59s
tcp-stats-filter-1.15-basic2       2m58s
tcp-stats-filter-1.16-basic2       2m55s
tcp-stats-filter-1.6-basic2        2m51s

with 2.3

NAME                               AGE
metadata-exchange-1.6-basic2       10s
stats-filter-1.11-basic2           13s
stats-filter-1.12-basic2           12s
stats-filter-1.13-basic2           12s
stats-filter-1.14-basic2           11s
stats-filter-1.15-basic2           11s
stats-filter-1.6-basic2            9s
tcp-metadata-exchange-1.6-basic2   9s
tcp-stats-filter-1.11-basic2       12s
tcp-stats-filter-1.12-basic2       12s
tcp-stats-filter-1.13-basic2       11s
tcp-stats-filter-1.14-basic2       11s
tcp-stats-filter-1.15-basic2       10s
tcp-stats-filter-1.6-basic2        9s

I know in 2.5 we went to istio 1.18 and in 1.18 that stats-filters should not be installed by default and telemetry is used instead

but why then are filters from 1.6 still being generated even in 2.5?
