DEPR: copy argument in DataFrame/Series.tz_localize/tz_convert

[mroeschke]

ref: #24657 (comment)

The copy argument in these methods should be deprecated in favor of inplace to be consistent with other methods.

[jorisvandenbossche]

Whether we want to do this or not might depend on the discussion in #16529

[jbrockmendel]

the future of 'copy' depends on CoW, but i think we're agreed against implementing more inplace keywords. closeable?

[mroeschke]

Yeah agreed that probably shouldn't be replaced with inplace but copy here should get the same treatment as your similar PRs for methods that only effect the index?

Not sure what you mean. tz_convert/tz_localize already make shallow copies when copy=False

[mroeschke]

Ah gotcha. Nonetheless your original point stands as copy should be kept in favor of inplace
