OneDrive Message Center Updates January 15th to January 31st

If I'm reading this correctly, this is a HUGE problem for us. Per the Message Center notification:

• The Site theme selected for a specific SharePoint site through https://support.office.com/article/change-the-look-of-your-sharepoint-site-06bbadc3-6b04-4a60-9d14-894f6a170818 will no longer be applied to the navigation bar. The updated navigation bar will now be consistent as you navigate through a site, SharePoint Online and the Office 365 suite of apps (OneDrive for Business, Outlook.com, Office.com, etc.). The navigation bar theme will show the user-personalized theme, if one is selected. If there is no personalized theme, the navigation bar theme will follow either the Organizational Profile or the OneDrive for Business/SharePoint Online brand color (blue).

We rely heavily on the uniqueness that Change the Look Settings offers for each site [collection] and how it is to inherit from the hub site to other related sites. Our business cannot have a unified branding experience across all sites. We need to be able to override a personalized theme, on a per site [collection] basis, if/when requested. The differentiation created by the Hub based branding that is inherited to other linked sites is a major communication tool for our company.

Please tell me I'm reading this wrong and that unique hub site/connected site branding is still an option and that we can override personalized themes on a per hub (and its linked sites) basis.  If I'm right, then I need to know how to stop this 'improvement' for our tenant.
