url rewrite to avoid third level domain still make sense?

Hello everyone. I've been using f5 in a simple way for some years - I'm not an expert - but i have always implemented the visibility of sites with third-level domains
for example: https://company.com/test -> redirect to https://test.company.com for my application or site.
Now the business request has changed, they no longer want to see the third level url (https://test.company.com/) but always https://company.com/test/ecc.ecc.ecc
i suppose i should implement heavy url rewrite rules.
The question is, the url rewrite to avoid third level domain still make sense, is it still valid, or does it turn out to be deprecated for some reason? or for simplicity the third level domain remains the best solution?

Thanks to everyone
Alberto
