Glad that we have these aliases and it doesn't break anyone. Is there a work item for manifest get instead of manifest fetch to align with the renames?

I am okay to replace oras manifest fetch with oras manifest get. cc @shizhMSFT @FeynmanZhou

Closing this PR since remove and delete means different things: delete means erase (i.e. rendered nonexistent or nonrecoverable), while remove denotes take away and set aside (but kept in existence).

Since user cannot undo oras manifest/blob delete via oras commands, we should avoid using remove in the example to avoid confusion. But it's okay to add it a alias, which is done in #677

Nope, the work item isn't there right now. The problem with the word get is to find out its opposites in terms of UX.

• oras manifest get -- oras manifest set does not sound right.
• oras manifest get -- oras manifest put sounds right but oras blob put is a bit strange since blobs are usually large.

For now, we have oras manifest fetch -- oras manifest push. The idea can be viewed similar to git fetch v.s. git pull where fetch will not change local filesystem but pull does. Anyway, we already have oras manifest get as an alias of oras manifest fetch. So... feel free to use oras manifest get.
