That's quite heavy a change... This move from pandas seems an unnecessary leap to me! |

Pandas has introduced some deprecations in how frequency strings are specified:
"A","A-JAN", etc. in favor of"Y","Y-JAN", etc. (DEPR: 'A' for yearly frequency and YearEnd in favour of 'Y' pandas-dev/pandas#55252)"AS","AS-JAN", etc. in favor of"YS","YS-JAN", etc. (DEPR: ‘AS’, ‘BA’ and ‘BAS’ in favour of ‘YS’, ‘BY’ and ‘BYS’ pandas-dev/pandas#55479)"Q","Q-JAN", etc. in favor of"QE","QE-JAN", etc. (DEPR offsets: rename 'Q' to 'QE' pandas-dev/pandas#55553)"M"in favor of"ME"(DEPR: deprecate strings T, S, L, U, and N in offsets frequencies, resolution abbreviations, _attrname_to_abbrevs pandas-dev/pandas#54061)"H"in favor of"h"(DEPR: deprecate string H, BH, CBH in offsets frequencies, resolution abbreviations, _attrname_to_abbrevs pandas-dev/pandas#54939)"T","S","L", and"U"in favor of"min","s","ms", and"us"(DEPR: deprecate strings T, S, L, U, and N in offsets frequencies, resolution abbreviations, _attrname_to_abbrevs pandas-dev/pandas#54061).It would be good to carry these deprecations out for cftime frequency specifications to remain consistent.
