Originally slated for 6.2.15 release as
https://git.magnolia-cms.com/projects/DOCUMENTATION/repos/product-docs/pull-requests/803/diff#modules/ROOT/images/MAGNOLIA-8092-maxAliasesForCollectionsInYaml.png

but reopened.

(From Dai):

now under config/config
 
'yamlReaderConfiguration':
{{ 'jcr:primaryType': 'mgnl:content'}}
{{ 'maxAliasesForCollectionsInYaml': '50'}}
 
 
so we have that kind of structure
and it is bootstrap directly to config workspace

instead of yaml config like before
so our recommendation is that, do not use decoration to modify that value
 
config it directly via Configuration app
otherwise we will have order problem - old value will be used to read yaml file - before our decoration kick in and adapt the new value
