I think we need to state issues in terms on impact on clients of CLDR, not the nitty-gritty internals.

Suggested change

	(as for use in a table). Some further adjustments were needed ([CLDR-17879](https://unicode-org.atlassian.net/browse/CLDR-17879)):
	- Adjust coverage so that these variants are at moderate (not comprehensive) coverage for standard/accounting currency formats with
	`numberSystem="latn"`, and so that `alt="alphaNextToNumber"` is at modern (not comprehensive) for oither relevant number systems in
	in a locale. Coverage was already correct for other combinations of these attributes with various numberSystems.
	- Adjust PathHeader so compact currency for relevant non-Latn number systems in a locale will appear in Survey Tool.
	- In root, add an `alt="alphaNextToNumber"` variant for the standard/accounting currency patterns.
	- Ensure that in the most commonly-used locales. for all relevant number systems in the locale, the standard/accounting currency
	patterns have both `alt="alphaNextToNumber"` and `alt="noCurrency"` variants (inherting as necessary), and the compact currency
	formats have the `alt="alphaNextToNumber"` variants.
	(as for use in a table). Gaps in the data coverage showed up, because the translators weren't shown the right values.
	Fixes were made in [CLDR-17879](https://unicode-org.atlassian.net/browse/CLDR-17879).
