TYPO3 9.5.4 (with slug) ignores get parameter 'type'

Question

I want to switch the type of my typo3 website eg for xml or json output, but the system ignores the get parameter type. I don't know what I'm doing wrong or if there is a bug.

typoscript example

testtype = PAGE
testtype.typeNum = 13
testtype.10 = TEXT
testtype.10.value = test
testtype.config.disableAllHeaderCode = 1

my site config

You make use of the PageType routeEnhancer, when that is active you have to map all the page-types you use. Otherwise it gets stripped from the url.

Also, the PageType routeEnhancer should be the last enhancer you configure, as it modifies existing route variants: https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/core/Classes/Routing/Enhancer/PageTypeDecorator.php#L25
