Bikeshed: name of the "min2" option

[sffc]

What should we call the "min2" option for useGrouping? (context: #3)

1. "min2" (keep it as proposed)
2. "minimum2" (suggested by @FrankYFTang)
3. "partial" (suggested by @sffc)
4. Others?

[FrankYFTang]

To be clear, I have no opinion about the "name" but rather the "naming convention" of the value of the option. In other part of ECAM402, we use
""best fit" for all Intl objects, (not "best-fit, nor "bestFit" nor "besFit" )
"2-digit" in Intl.DateTimeFormat (not "2Digit", nor "2dig"
"exceptZero" in Intl.NumberFormat (not "except-zero" nor "excZer" )

"min2" , which truncate the first three letter of "minimum" then join with "2" seems yet another new naming convention to me.

"minimum 2" or "minimum two" would be align with "best fit"
"minimum-2" would be align with "2-digit"
"minimum2" or "minimumTwo" would be align with "exceptZero"

but "min2" will be a new kind.

Or "minimumTwo", most like "exceptZero"?

@justingrant also draws a comparison with h12 and h24. "min2" is similar to those.
