characteristics : availability, resilience, authenticity, quality, usability

According to the trustworthiness definition in 24028, included Note2.
"Note 2 to entry: Characteristics of trustworthiness include, for instance, reliability (3.30), availability, resilience, security (3.35), privacy (3.28), safety (3.34), accountability (3.1), transparency, integrity (3.21), authenticity, quality, usability."

Isn't there a need to add the below characteristics:

• availability
• resilience
• authenticity
• quality
• usability

First I think it would be better to anchor this analysis on the definition of trustworthiness published in ISO/IEC 22989:2022 and the definition in DTS 5723 (see WG3 N2729) especially since DTS 5723 provides definitions for this missing characteristics.

From ISO/IEC 22989:2022:

3.5.16
trustworthiness
ability to meet stakeholder (3.5.13) expectations in a verifiable way

Note 1 to entry: Depending on the context or sector, and also on the specific product or service, data and technology used, different characteristics apply and need verification to ensure stakeholders’ (3.5.13) expectations are met.
Note 2 to entry: Characteristics of trustworthiness include, for instance, reliability, availability, resilience, security, privacy, safety, accountability, transparency, integrity, authenticity, quality and usability.
Note 3 to entry: Trustworthiness is an attribute that can be applied to services, products, technology, data and information as well as, in the context of governance, to organizations.

[SOURCE: ISO/IEC TR 24028:2020, 3.42, modified — Stakeholders’ expectations replaced by stakeholder expectations; comma between quality and usability replaced by “and”.]

From DTS 5723:
3.1.1
trustworthiness
ability to meet stakeholders’ (3.3.9) expectations in a verifiable (3.3.12) way

Note 1 to entry: Depending on the context or sector, and also on the specific product or service, data, technology and
process used, different characteristics apply and need verification to ensure stakeholders’ expectations are met.
