I don't understand your concern. Could you please elaborate on what you
mean by "why we should ignore it here"? What is the "it" and what is
the "here"?

The HTML export backend can create such text areas. It requires an
‘#+ATTR_HTML’ line as shown in the example below with the ‘:textarea’
option. This must be followed by either an example or a source code
block. Other Org block types do not honor the ‘:textarea’ option.
#+end_quote
The current processing of :textarea does special handling for width and
height attributes and discards the rest (based on my understanding of
the code in `org-html--textarea-block'). Said support for :textarea
attribute exists in `org-html-src-block' and `org-html-example-block'
which is consistent with the manual.
The patches I shared did not interfere with the handling of :textarea in
the blocks that support it.
In order to make the code more robust, one may wish to remove :textarea
from the list of attributes (or issue a user-error or warning if it's
present) in blocks that were never intended to support it (such as
`org-html-fixed-width'). I do not have any opinion on this matter.
Similarly, one may wish to add additional error checking based on the
specifics of the transcoded element. I do not believe this to be
worthwhile (HTML validation often has errors, and if a user is so
interested they always have the option of validating the generated
HTML).
There is an open question regarding what attributes to support in
`org-html--textarea-block' (i.e., in the presence of `:textarea'
option). I believe the "correct" thing would be to filter out `:width'
and `:height' (since, if present, they are translated into `rows' and
`cols' attributes in the generated HTML) and include the rest "as is" in
the generated HTML
Regardless of the specifics above regd. :textarea, I believe support for
#+ATTR_HTML ought to be added for most blocks to allow for CSS class
and/or inline style to be specified when exporting to HTML.
Additionally, I consider the absence of such support to be a bug.
