DOC: Remove inplace from user guide
This starts with removing inplace from the user guide

Just a thought: do we want to add any note/guidance somewhere for folks who might be looking specifically for inplace? Are these errors expected? (in: `advanced.rst`, local build)

Everything else generated without errors. > Just a thought: do we want to add any note/guidance somewhere for folks who might be looking specifically for inplace?

Was thinking of writing up the PDEP and then linking the discussion in the whatsnew. There could be a better way though

Thx for catching, did not pay enough attention when modifying the examples. Fixed now > > Just a thought: do we want to add any note/guidance somewhere for folks who might be looking specifically for inplace?

@phofl Can you DM me on slack? I was also thinking about writing up a PDEP (didn't get too far though). Everyone ok with going ahead and merging? Thanks @phofl
