I think it improves website usability when they are navigatable via the URL.
For example when viewing Posts under the caetegory 'Tech' ie https://lizard-spock.co.uk/category/tech.html,
removing the category and viewing https://lizard-spock.co.uk/category/ should list the possible categories.
The page is created by pelican but it is placed as :
https://lizard-spock.co.uk/categories.html
Not
https://lizard-spock.co.uk/category/index.html
To remedy this, modify your pelicanconf.py Adding in some page mappings.
## Adding template pages creating /tag/index.html from tags.html
TEMPLATE_PAGES = {'tags.html': 'tag/index.html'}
The Above takes the tags.html template and makes it available via example.com/tag
